From all those who lost their lives on 9/11, Welles Crowther was the only one to be mentioned by name during Tuesday's ceremony. The 24-year-old investment banker had applied to be a New York firefighter. He was later identified as "the man in the red bandana," who helped save at least five and as many as 18 people that day.

L.A. Mayor Eric Garcetti spoke about strength in the years since, with a message to never forget.
